Please look at this thread which will explain why Freebuild is in maintenance:
https://www.cubecraft.net/threads/free-build-extended-maintenance.50080/
It is not easy to rewrite games from scratch.
If you're wondering "
If they are able to make new games such as Blockband, why don't they focus on the ones in maintenance first?"
Not all devs work on the same project - some of them have their own.
You can also say they have their own priorities.
I won't say it's "
soon" or "
coming soon" as we
do not have a release set date nor do we know when will it be out.
I do not want to give you guys any false hopes but you can always check back for updates.
If you're not active on the forums, try checking once a week at least.
Thanks for understanding.
